That's about as good of a start as I can think of, Deco. Welcome to the forum.

I don't think you can go wrong with either of those Gillettes. They shave pretty similarly, in my experience. The Tech is a 3 piece razor and the SS has a little more weight to it and is twist-to-open. Find a nice, user-grade one for less than $15.

Try a 1912 Gem Razor, a Gillette New from the 1930s, a Gem G-Bar from the 1930s, a Gillette Superspeed, and then a Gillette Adjustable. Then, you can get an Injector and by then you will have covered most of the "vintage".

Hello and welcome to The Shave Nook. I would suggest that you bypass all the double edge Bull Dinkey and jump right into Single Edge. Save yourself a bunch of heartache. Get yourself a GEM Featherweight and enjoy the ride..... Happy Shaves !!!!
